The ONLY car that was ORIGINALLY produced in a different colour to white was Dianas black one.
The red/grey/pink/purple ones were ALL orginally WHITE and resprayed at a later date.
A guy still owns Dianas old S1, it was won on a radio station then sold on to a chap called J Windsor off the RSOC.
He has been offered a serious was of cash for it, but would sell it 'if the price was right'.
